Abstract
A bushing kit and a method of installing the same with a mandrel having a tapered region. The bushing kit includes an inner member and an outer bushing. The inner member may include an inner surface having an engagement portion, such as a coating, plating, and/or lining, such as a self-lubricating coating. The method of installing the bushing kit includes passing the tapered portion of the mandrel through the outer bushing to radially expand the outer bushing into the structural workpiece and possibly induce some amount of residual compressive stress in the structural workpiece. Contemporaneously, the inner member is passed into the radially-expanded outer bushing before the outer bushing is permitted to radially inwardly rebound or spring back. The outer bushing is then permitted to radially contract onto the inner member to form an interference fit therewith.
